NGC 7635: Bubble in a Cosmic Sea
Explanation: Adrift in a cosmic sea of
stars and glowing gas the delicate, floating apparition left of center in this widefield view is cataloged as NGC 7635, the Bubble Nebula. A mere 10 light-years wide, the tiny Bubble Nebula was blown by the winds of a massive star. It lies within a larger complex of interstellar
gas and dust clouds found about 11,000
light-years distant, straddling the boundary between the parental constellations
Cepheus and
Cassiopeia. Included in the breathtaking vista is open
star cluster M52 (lower left), some 5,000 light-years away. Above and right of the Bubble Nebula is an emission region identified as
Sh2-157, also known as the Claw Nebula. Constructed from 47 hours of narrow-band and broad-band exposures, this image spans about 3 degrees on the sky. That corresponds to a width of 500 light-years at the estimated distance of the
Bubble Nebula.
